I just purchased a 1991 Supra Mariah and cannot get the oil light and audible alarm to shut off. I have checked the oil...fine! The oil gauge reads perfect, and so is the engine temp. We changed the oil pressure sending unit, with no result...still squealing! It only does it when the engine is warmed up. Besides by-passing it all together, does anyone have any suggestions for me to try?
THANKS!!!
